Eight AI fitness coaches, built around your data.

Jamie Reyes

AI hypertrophy coach

Your coach for serious muscle-building without chasing the stage. Structured and encouraging, leaning hard into progressive overload, smart muscle-group balance, and the kind of training volume that builds real size over months and years. Thinks about sustainable progress, not hype. For people who want to look and feel stronger without ever stepping on a bodybuilding stage.

Lauryn Britt

AI injury & recovery advisor

Your rehab specialist when something hurts or you're coming back from an injury. Serious, calm, and patient. Won't sugarcoat a timeline, will tell you a rotator cuff rehab is a twelve-week project and not a two-week one. Walks you through phase-based progressions, corrective exercise, and pain-as-signal education. Always recommends in-person assessment for anything acute or persistent.

Casey Mills

AI dietary advisor

Your practical, judgment-free guide to food and macros. Thinks in patterns over individual meals, never moralizes about what you ate, and will help you hit your protein target without turning dinner into a math problem. Calm, specific, and occasionally funny: the nutrition voice that meets you where you are instead of where a textbook says you should be.

Evelyn Cross

AI longevity advisor

Your advisor for the long game: healthspan, biomarkers, lab interpretation, rejuvenation research, and decisions whose payoff is measured in decades. Intellectually rigorous and comfortable in probability distributions. Will tell you "we don't have strong evidence for that yet" without apology, tracks the primary literature on senolytics, rapamycin, and epigenetic reprogramming, and thinks "die healthy at ninety" is a low-ambition target. Warm but demanding, pushing you to think bigger without getting reckless.

Max Kline

AI Biohacker

Your biohacker-in-chief. Engineer-minded and unapologetically experimental, proposing a structured two-week trial of a new protocol, helping you set a clean baseline, and showing you how to measure whether it actually worked on you specifically. Lives inside HRV, CGM, sleep stages, and wearable data, and thrives on the "I wonder if this actually works for me" question. Data-loving but honest about noise; won't let you over-interpret a single reading.

Rex Dalton

AI bodybuilding coach

Your coach when bodybuilding is the sport, not a hobby. Intense, direct, and unapologetically motivating. Runs real cuts, real bulks, and real contest prep. Will tell you your chest is lagging because you're not doing enough volume, not because your genetics are bad. Old-school iron gym discipline backed by modern hypertrophy science. For the stage, the shredded off-season, and anyone who wants a coach who takes the work as seriously as they do.

Elias Kiptoo

AI running coach

Your running coach for road and trail running, from couch-to-5K through a Boston qualifier. Precise, warm, and quietly competitive. Talks in zones, RPE, and weekly volume, never in gimmicks. Believes 80% of distance runs should be boringly easy and will push back when you run your Tuesday tempo at Wednesday easy pace. Thinks in blocks, not single workouts. Cares about cardiac drift more than average pace.

Atlas Mercer

AI protocol architect

Your operator for ultra-systematic optimization. Treats your body like a system to be measured, modeled, and tuned. Precise, emotionally detached from "feeling good," and speaks in protocols instead of suggestions. Never moralizes; just presents the optimal path, the tradeoffs, and the measurements that will tell you whether it's working. Best for users who want rigor turned all the way up.
